Module Quick Check

NOTE: Before installing the optical cables, clean the optical fiber connectors on both the cable ends and the front panel connectors.

1.With proper in-line 15dB attenuator, connect a single mode optical cable between the Optical OUT and Optical IN connectors on the Optics card.

CAUTION! Signal levels greater than 0 dBm may damage the Optical Input devices. Always pad the input level to less than 0 dBm.

Always use 15dBm of attenuation when connecting the OTS9100 module transmit output to its receive input. Failure to do so will damage the optical detector.

2.If the instrument is not already powered on, start the system as described in the Power On and Software Initialization procedure of the previous section.

3.From the Menu Bar, click the System button; this opens a drop down menu. In the drop down menu select Signal Standard then select Set to SONET.

4.Transmitter Setup

From the Menu Bar, click on View and select System View. The System View should display an image with each card in position. Check this view to ensure that all the cards loaded are visible. Blue lines spanning across the cards represent the correct cabling for the configuration of cards loaded in the system. The System View window is meant to be used as a reference for verifying cards and cabling a system. It does not provide a means to determine live or dead cards.

5.Click the Setup Category bar in the Navigation window and select the OTS91T3 10Gb/s Tx+ #1 icon. The Setup Property Page associated with the selected icon should display.

6.In the Property Page window, select the Signal tab and make the following selections from the pull-down menus:

•Signal Source: Internal

•Timing Source: Internal

•Trigger Output: Anomaly

•Active Channel, Signal Structure: STS-1

•Active Channel, Test Pattern: PRBS 2^23-1 (ITU)

•Active Channel, 1

7.Select the Error Insertion tab and make the following selections:

•Anomaly Insertion Setup Type: None

•Defect Insertion Setup Type: None

8.Receiver Setup

In the Navigation window, keeping the Setup Category as the active category (always check the Title Bar of the Setup Menu to ensure that it is associated with the correct device), select the OTS91R2 10Gb/s Rx+ #1 icon and set the Receiver Threshold Offset level to 0 mV.

9.In the Navigation window, click on the Test Control Category bar and select the OTS91R2 10Gb/s Rx+ #1 icon.

10.Click the Edit Test Control Settings.
